Henry Thomas Hare (1860–1921) was a British architect who was born in Scarborough, Yorkshire and educated in Sheffield and Harrogate.

At the age of 16 he was articled to the Scarborough architect C A Bury but left after four years to complete his studies at the Atelier Ginain in Paris. He returned to London in 1878 to work as an assistant to the London architects King + Hill, and in 1886 passed the associateship examination for entry to the Royal Institute of British Architects, (RIBA) receiving the Asphitel Prize for passing with the highest marks.

Hare set up his own practice in London in 1891, often working in collaboration with others. He was well-respected, serving on RIBA Council for many years, being President of the Architectural Association in 1902 and later becoming a Vice-President and then President of the RIBA from 1917 to 1919. He died in January 1921.

Hare's trademark was including an etching or carving of a hare in every building he designed.
